摘要： Embodiments of apparatus, packages, computer-implemented methods, systems, devices, and computer-readable media (transitory and non-transitory) are described herein for ascertaining, e.g., by a traffic detection function (“TDF”), that a first user equipment (“UE”) and a second UE are, potentially, sufficiently proximate to each other to wirelessly exchange data directly. In various embodiments, an evolved serving mobile location center (“E-SMLC”) may be instructed, e.g., by the TDF, to obtain location change data associated with the first and second UEs. In various embodiments, a determination may be made, e.g., by the TDF, based on the location change data, whether the first and second UEs are sufficiently proximate to exchange data directly, and whether the first and second UEs are likely to remain proximate for at least a predetermined time interval. In various embodiments, the first and second UEs may be caused to commence device-to-device (“D2D”) communication based on the determination.

摘要： One aspect of the teachings herein relates to signaling codebook restrictions, to restrict the precoder recommendations being fed back from a remote transceiver, so that precoder selections made by the remote receiver are restricted to permitted subsets of overall precoders within a defined set of overall precoders, or to permitted subsets within larger sets of conversion precoders and tuning precoders, for the case where the overall precoders are represented in factorized form by conversion and tuning precoders. As a non-limiting example, these teachings advantageously provide for precoder restrictions in LTE or LTE-Advanced networks, where ongoing development targets the use of larger, richer sets of precoders, and where the disclosed mechanisms for determining, signaling, and responding to subset restrictions provide significant operational advantages.

摘要： A multiple-input multiple-output (MIMO) wireless communication systems that includes a plurality of adjacent cells, each containing one or more base stations operable to transmit signals to, and receive signals transmitted from, one or more users. The users are operable to feed back to the relevant base station(s) channel state information relating to channel(s) between the relevant base station(s) and the users, and the base stations are operable to adapt signals for transmission to users, based on the fed back channel state information, to account for channel variations. The proposed method involves obtaining information related to time-variation in channel spatial structure, and adjusting the timing with which a user feeds back channel state information, based on the time variation in channel spatial structure. The invention helps to achieve a suitable balance between the feedback overhead and system performance, and may be operable in systems operating according to various CoMP transmission modes.

摘要： A method for communication includes providing a first transceiver configured to communicate with a second transceiver over a bi-directional link having a first aggregation of frequencies that are assigned to carry first communication traffic in a first link direction from the first transceiver to the second transceiver and a second aggregation of frequencies that are assigned to carry second communication traffic in a second link direction from the second transceiver to the first transceiver. Communication feedback is transmitted from the first transceiver to the second transceiver communication feedback at an adaptive feedback rate. The feedback rate is determined so as to achieve a desired balance between the information carrying capacities of the first and second aggregations. An information carrying capacity of the second aggregation is controlled responsively to the communication feedback.
